this to sing with, as we shall say." For the rest, there 

 is nothing on the belly. When they are disturbed 

 and fly away, they give out moisture, which is the 

 only proof that they hve on dew ; moreover they are 

 the only creatures that have no aperture for the 

 bodily excreta. Their eyes are so dim that if any- 

 body comes near to them contracting and straighten- 

 ing out a finger, they pass by as if it were a leaf 

 flickering. Some people make two other classes of 

 tree-crickets, the twig-cricket which is the larger, 

 and the corn-cricket, which others call the oat-cricket, 

 because it appears at the same time as the crops 

 begin to dry. Tree-crickets do not occur where trees 

 are scarce — consequently they are not found at 

 Cyrenae except in the neighbourhood of the town — 

 nor in plains or in chilly or shady woods. These 

 creatures also make some ditference between locah- 

 ties ; in the district of Miletus they occur in few 

 places, but there is a river in Cephallania which makes 

 a boundary with a few of them on one side and many 

 on the other ; again in the Reggio territory they are 

 all silent but beyond the river in the region of Locri 

 they sing. They have the same wing-structure as 

 bees, but larger in proportion to the body. 



XXXIII. Of insects some have two wings, for '5'"!<^""'« <>/ 

 instance, flies, and some four, for instance bees. irisects. 

 The tree-cricket also flies with its membranes. 

 Those armed with a sting in the belly have four wings, 

 but none having a weaponin the mouth has more than 

 two wings to fly ^vith, for the former have this weapon 

 bestowed on them for the sake of vengeance but the 

 latter for the purpose of greed. No insects' wings 

 when torn off grow again. None that has a sting in 

 the belly is two-winged.
